Discontinued?

For the past year, I've been monitoring the website, as I am planning on buying a bunch of PC parts in the nearest future. I've been ready to make a purchase for a couple of months already, but some items just seem to be gone and completely unavailable. I am specifically talking about the Tomahawk ATX, 360-mm Hanbo and Kunai. Will they ever be available, or are they discontinued? Maybe some of you has information? Thank you
